How to improve the credit rating of enterprises and AAA certificate of bidding qualification? Formal national certification?

I remember my colleague did this aaa certification before, and it was done with a small program. It seems to be called Run Zheng Tong. I found it on Alipay and WeChat, entered Run Zheng Tong, and then chose AAA authentication. After filling in the information, the customer service lady will contact in time, which is much more convenient than running offline to a physical store. He said it would be soon, and he received it the next day. Remember to like it. Get to know it quickly
